Abstract
A hydraulic unit includes a hydraulic pump and control valve on the mould closure unit of a plastic injection moulding machine, at least one hydraulic cylinder for building up pressure to keep the mould closed and to open it, and an equalisation cylinder. The speed and pressure profile of the closure movement can be specified by a 4/4 way valve. In the valve, the position of each stationary piston is determined. The profile of the closure movement is determined via a differential positioning unit.
